The very blessed Athanasius, also, Bishop of Alexandria, when contending against the Arians, who affirm that the Father alone is invisible, but suppose the Son and the Holy Spirit to be visible, asserted the equal invisibility of all the Persons of the Trinity, proving it by testimonies from Holy Scripture, and arguing with all his wonted care in controversy, labouring earnestly to convince his opponents that God has never been seen, except through His assuming the form of a creature; and that in His essential Deity God is invisible, that is, that the Father, the Son, and the Holy Spirit are invisible, except in so far as the Divine Persons can be known by the mind and the spirit. Gregory, also, a holy Eastern bishop, very plainly says that God, by nature invisible, had, on those occasions on which He was seen by the fathers (as by Moses, with whom He talked face to face), made it possible for Himself to be seen by assuming the form of something material and discernible. 1 Our Ambrose says the same: "That the Father, and the Son, and the Holy Spirit, when visible, are seen under forms assumed by choice, not prescribed by the nature of Deity;" 2 thus clearing the truth of the saying, "No man hath seen God at any time," 3 which is the word of the Lord Christ Himself, and of that other saying, "Whom no man hath seen, nor can see," 4 which is the word of the apostle, yea, rather, of Christ by His apostle; as well as vindicating the consistency of those passages of Scripture in which God is related to have been seen, because He is both invisible in the essential nature of His Deity, and able to become visible when He pleases, by assuming such created form as shall seem good to Him.
